河网汇流 concentration of river network
- 河网汇流采用隐式差分格式。
Drainage confluence is calculated by implicit difference scheme. - 流域汇流是一个三维水文学问题,主要依赖于流域的河网地貌和河槽动力特征。
Watershed flow concentration is a three dimension hydrological phenomenon, mainly concerning with thelandforms in river network and dynamic characteristics in river channels. - 进而将城市产汇流方法和河网水动力学方法相耦合,计算出在不同规划条件下的河网洪水位,以此为防洪规划工程提供技术支持。
At last, river water level in different plan condition is calculated integrating the method of city runoff and river network hydraulics, to provide technical supports for flood-prevention projects.
